Comparative analysis of the CNTs nano fluid flow between the two gyrating disks

Abstract

Nanofluids play a prominent role in the development of various electronic structures and technological devices. Herein, we devise new and efficient techniques for overcoming the problems faced by the base fluids. This article describes water-based carbon nanotubes, including two major types of single-wall carbon nanotubes (SWCNT) and multi-wall carbon nanotubes (MWCNT). A mathematical model is considered for unsteady three-dimensional CNTs nanofluids flow with a uniform magnetic field between two revolving disks. The basic equations of the modeled flow problem are solved by the BVPh 2.0 package which is implemented using the Optimal Homotopy Analysis Method (OHAM). It has been observed that by stretching the top disk while keeping the lower disk stationary, the rotation aspect is reduced, whilst radial velocity near the top disk significantly increases. Moreover, The higher the values of unsteadiness parameter, the more accurate the temperature profile.

Enhanced Heat Transfer in Vertical Channels via Non-Darcy Flow with SWCNTs and MWCNTs: Arrhenius Activation and Viscosity Variations

“…A comparative analysis is showcased between SWCNTs and MWCNTs suspended in a base liquid 27,28 . Some researchers 29,30,31 discussed the Single-wall carbon nanotubes (SWCNT) and multiwall carbon nanotubes (MWCNT), the two primary forms of water-based carbon nanotubes. A three-dimensional CNT nanofluid flow model with an unsteady flow and a uniform magnetic field between two rotating discs and also a Darcy-Forchheimer scheme with convective boundary conditions, suction/injection, and thermal radiation are considered 32 .…”

Significance of Nanoparticles Aggregation with Cattaneo-Christov Heat Flux on the Water and Ethylene Glycol Mixture Based MWCNTs-Nanofluid Flow over a Stretching Cylinder

“…The numerical estimates of the temperature gradient are shown to be diminishing for the convective dissipation effect. Khan et al [2] obtained the analytical solution of the unsteady CNTs nanofluid flow across two gyrating disks. The temperature distribution is assumed to be more accurate the stronger the values of the unsteadiness parameter.…”

Heat and mass transfer analysis of MHD stagnation point flow of carbon nanotubes with convective stretching disk and viscous dissipation

“…They discovered that the rates of entropy generation decreased when the radiation parameter was increased. Several authors [23][24][25][26][27][28][29] recently provided heat and mass transfer analyses of nanofluid flow among a variety of geometries. Since that time, a significant amount of research that takes MHD into consideration has apparently been carried out, as shown by Al-Kouz et al, 30 Bin Mizan et al, 31 Salawu et al, 32 Shamshuddin et al 33 However, the references that were discussed before only addressed the flat plate surface, there are still voids that may be filled in order to meet the criterion for further investigation.…”
